The report lists carbon fiber as just one of many potential coal products likely to see increasing demand in the 21st century. Other uses include advanced prosthetics, biosensors, electrodes, fertilizers and as a medium for 3D printers. And at a cost of $12 to $50 a ton versus nearly $500 a ton for petroleum, Atkins believe coal could find mass appeal again as further uses and innovations are discovered.
“As this becomes more widely known, I think we’ll see some fascinating breakthroughs in materials science,” he said. “Twenty or 30 years from now we may look back and say ‘My gosh, the 2020s were when we switched from widespread use of steel and aluminum to widespread use of carbon fiber from coal,’ that’d be huge.”
If and when those breakthroughs occur, Atkins hopes they’ll be under the roof of iCAM, or the Carbon Advanced Materials research park currently under construction in Sheridan. There, Ramaco Carbon plans to host researchers “from national laboratories, universities, private research groups and manufacturing organizations” in a collaborative effort to unlock the potential of coal’s carbon content.
Ultimately, Atkins’ plan is to develop an entire “Carbon Valley” akin to northern California’s Silicon Valley, with both research and manufacturing facilities fed by an adjacent coal mine.
That proposed coal mine, the Brook Mine, would be the first new coal mine in Wyoming in half a century, and one Atkins said would be relatively tiny compared to some of the extant mines in the state. But it has yet to materialize after Wyoming’s Environmental Quality Council rejected the mine’s permit application in September 2017 amid concerns over the potential environmental impacts. Ramaco’s appeal of that decision was heard in state district court in Cheyenne earlier this month, even as the company has submitted a revised permit application to the Department of Environmental Quality.
Even if the mine is ultimately approved, and in spite of his optimism about coal’s potential, Atkins says he doesn’t expect carbon fiber production will be what reverses the drop in severance taxes – at least not in the short-term. But in time, he believes coal’s high-tech uses could be what keeps mining a viable industry in the worst-hit parts of the state.
“As products develop over time … mines that can’t make it selling their coal at $12 to $15 a ton may be able to make it if they can sell at $25 to $40,” Atkins said. “I’m hopeful over a medium-term period this will provide an alternative demand for coal beyond its use as thermal coal.”
Travis Deti, executive director of the Wyoming Mining Association, believes Atkins’ proposals have promise, even if they don’t immediately offset the recent declines in production.
“What Ramaco’s doing with carbon fiber, graphene, graphite, 3D printing, that’s a great way to use our resource and make it viable in the future,” Deti said. “Is it going to replace the 300 million tons we’re mining right now? Probably not. But it’s an innovative use of the resource and it’s a great project.”
Deti said that while coal is still widely used internationally, especially in the Asia-Pacific region, it remains a hard sell domestically. While techniques for capturing and sequestering carbon dioxide from coal-fired power plants are still developing, he said, it’s important for stakeholders in the coal economy to find alternative uses of the mineral.
“We want to continue to use our coal for electricity generation, but it’s really a remarkable resource,” Deti said. “And looking at the direction of where we’re going right now in terms of electricity generation … we need to start looking at other avenues and ways of using the resource.”
